What it does
Suppressing Noisy Errors is an agent skill from PostHog/posthog, published by the product's own GitHub organization. Create PostHog error tracking suppression rules to drop high-volume, low-value errors at ingestion. Use when the user asks "stop capturing this error", "drop browser extension errors", "ignore ResizeObserver loops", "suppress bot-driven errors", or wants to reduce ingestion cost from noisy unactionable errors. Identifies suppression candidates, scopes the filter tightly, decides between full suppression and sampling, and confirms the rule before creating it. Suppressed errors are dropped permanently — this skill…
Its SKILL.md is about 4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Browser extensions. It works with PostHog and Chrome Extensions. The repository describes itself as: :hedgehog: PostHog is the leading platform for building self-driving products. Our developer tools – AI observability, analytics, session replay, flags, experiments, error…
When your agent uses it
- The user asks stop capturing this error
- Drop browser extension errors
- Ignore ResizeObserver loops
- Suppress bot-driven errors
Example prompts
- “stop capturing this error”
- “drop browser extension errors”
- “ignore ResizeObserver loops”
- “/suppressing-noisy-errors”
Workflow steps
7 steps, taken from the step headings in SKILL.md.
- Identify candidates
- Confirm the pattern
- Scope the filter tightly
- Decide: suppress or sample
- Dry-run the filter against live data
- Confirm with the user before creating
- Watch the rule for 24-48h
What it can do on your machine
Read from SKILL.md and the folder at commit 10f9ad7. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are json and sql).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Suppressing Noisy Errors loads about 4k tokens when it runs. Until then it costs about 141 tokens; SKILL.md has 1,671 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,671 words (~3,981 tokens).
“Suppression is destructive in spirit: matching events are dropped at ingestion and never become issues. The wrong rule silently throws away real bugs. This skill exists to make sure suppression is applied only to patterns that are genuinely unactionable, with…”
